This invention relates to window structures of the character usually employed in buildings where the sashes thereof are relatively slidable to open and/ or close the window opening and where it is usually desirable to maintain the sashes in a position where the window is partially or completely open.

The primary aim of this invention is to provide window structure of the aforementioned character wherein the upper and low r sashes thereof may be completely removed from their normal position within the Window frame either for the purpose of cleaning the glazing or for other reasons prompted by the necessity for servicing some part of the window structure where th sashes thereof are not in a convenient location when left in the window frame.

A further object of this invention is to provide window structure, the parting rails whereof are removably maintained in place Within the window frame through the medium of uniquely arranged fixtures, the character whereof is such as to permit the removal of the parting strips without the employment of tools and without manipulating nails, screws or other fastening elements, none of which ar employed in maintaining the parting strips in place. 7

A yet further object of this invention is to provide a window structure with a number of part ing strips, all quickly removable and provided with resilient means for engaging the slidable window sash; to maintain the said sash in any desired position along their paths of travel; and further to hold the sash securely, yet slidably in position within the window frame.

Further aims and objects of this invention include the precise manner in which the parting strips are formed; the way in which said parting strips cooperate with the specially designed fixtures; and the disposition of the parting strips to allow the same to act upon both the upper and lower window sashes, all as will be more fully hereinafter set down and described in the specification, referring to the accompanying drawing, wherein:

Fig. 1 is a condensed elevational view of window structure made in accordance with the present invention.

Fig. 2 is an enlarged, fragmentary, detailed sectional view taken on line 11-11 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a similar detailed, sectional view taken on line III-I1'I of Fig. 1.

Fig. 4 is a fragmentary, perspectiv view illustrating the component parts of the parting strip.

1 Claim. (Cl. 16-220) Fig. 5 is a perspective view of the fixture for holding the parting strip in place; and

Fig. 6 is a perspective view of the fixture shown in Fig. 5 illustrating the parts of the said fixture in a position where the parting strip may be removed from its normal position.

So far as I am aware, there has never been a window structure provided with means for yieldably maintaining the sashes thereof in a desired position, which means is entirely removable from association with the window frame and sash s for the purpose of removing the latter from the frame to wash the window pane. I am also unaware of any window structure having parting rails for holding the slidable window sashes in place, which rails may be made in relatively long strips and cut to the desired length when the window is to be assembled, the said parting strips having resilient means or springs for engaging the slidablewindow sashes.

In the form of th invention illustrated in the drawing, the window structure is capable of such manipulation as to allow the complete and expeditious removal of both the window sashes when washing is to take place and in the event it is desired to render unobstructed the entire opening formed by the window frame, the sashes may be removed from place and allowed to remain out of the operative position to prevent a completely unobstructed window opening formed by the frame.

The frame is broadly designated by the numeral Ill and the sashes slidably mounted therein are indicated by the reference numerals l2 and M. The upper sash numbered l2, rides against a strip [6 rigid to window frame In along the outermost portion thereof. It is the outer face of upper sash l2 that rides against strip l6 while the inner face of upper sash l2 bears directly against the undulated spring [8 confined within parting strip 20. This parting strip is shown in detail in Fig. 4 and is precisely the same as the strips later to be described when referring to the manner in which lower sash I4 is slidably held in place within frame l0.

Parting strip 20 has a fixture 22 holding the lower end thereof against the outer surface of lower sash M as illustrated in Fig. 3. This lowermost fixture holds the smooth side of parting strip 20 against the outer face of lower sash l4. while th undulations of spring [8 have a strip bear against the inner face of lower sash I I. The upper end of parting strip 20 is held in place by a fixture positioned on the opposite side of the parting strip from that fixture shown in Fig. 3

and therefore, the parting strip 20 is held in place without unduly restricting th movement of upper and lower sashes l2 and M. In other words, when upper sash I2 is moved down along parting strip 20, its downward movement is limited by the outer fixture 22 disposed very close to the bottom of parting strip 20. When inner sash I4 is raised, the upper portion thereof will strike fixture 22 shown in the upper portion of Fig. 1 and the upward movement of lower sash M will be limited by the said upper fixtures. The position of these said fixtures is such however, as to create no objection for the full path of travel of the sashes may be traversed with the possible exception of an inch or two occupied by the lower outer fixture 22 and the upper inner fixture 22.

The innermost strip 24 has the fixtures which hold the same in place along the inner edge thereof and the open side of the channel from which the strip 24 is constructed faces the inner surface of lower sash It, as illustrated in Figs. 2 and 3.

The spring 18 is precisely thesame as the similar spring in parting strip 26 and as a matter of fact, parting strip 29 and strip 24 are exactly the same in construction. This structure is shown in Fig. 4 and when the strips are manufactured, the same are channel-shaped in cross-section with the undulated spring I9 held in place by rivets or the like 26 that pass through the base of the strip body.

All of the fixtures are of like character and are clearly shown in Figs. and 6 to comprise a section 28 having openings 30 therein through which screws or other fastening elements may be passed to enter the window frame It) when the fixtures are mounted. A swingable section 32 is L-shaped in form and may be swung to the position shown in Fig. 6 from that position shown in F g. 5. The strip 26 shown in dotted lines in Fig. 5, may be, either the parting strip 20 or the strip 24, dependin upon the location in the assembly. An angular finger 34 pivotally mounted as at 36 to section 28 of fixture 22 swings to a position where section 32 is held in place against either the parting strip 20 or strip 24 and when section 32 is swung to the position shown in Fig. 6, the strips may be. moved away from frame It to permit the displacement of sashes l2 and I4.

An ear 3B struck from section 32, limits th movement of finger 34.

When th parts 01' the window structure above described and shown in the accompanying drawing are together, the sashes are yieldably held in any desired position along their paths of travel; the sashes will not rattle nor allow the entrance of the elements into the building equipped with the window structur and the sashes may be removed frcm their operative position for such maintenance as may be necessary.

Window structures made in accordance with this invention may b installed in buildings when originally erected or the window sashes and frames of buildings already in existence may be equipped with the parts above described to the end that the benefits arising from the invention may be enjoyed.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

A holding device for window strips com rising a pair of sections; interfitting hinge barrels on said sections; a hinge pin for said barrels; and a finger swingable on one of said sections on. an axisperpendicular to. said hinge pin, the other section being L-shaped and having the outer leg. thereof normally parallel to and extending oppositely from said, one section, said finger having. an L shaped portion intermediate the ends thereof for clearing said hinge barrel and a second L-shaped portion adjacent the free end thereof in normal overlapping engagement with the legs of said other section.
